Vial Cleaning

To ensure accurate results, all vials should be freeof fingerprints and smudges prior to placing in thevial block for equilibration. All vials should becleaned prior to use.

• Holding the vial by the cap, immerse the lowerportion of the vial (about 2.5 cm) into cleanisopropyl alcohol.

• Remove the vial from the alcohol and gentlywipe the lower portion of the vial by rotating thevial against a lint-free wipe.

Disposal

• All PCS reagents are non-hazardous and aqueousbased.

• Small quantities may be disposed of in sewer. Largequantities should be disposed of in accordance withlocal, state or federal regulations.

If Reagent Kit has been moved from another location,depending on the difference in temperature betweenthe two locations, an hour may be required forequilibration.

Removing the kit components from the box andletting them stand in free air will hasten equilibration.

Storage

• The Reagent Kit should be stored at room temperature(18-28° C).

• Avoid temperatures exceeding 32° C.

• Kits should be stored in the dark to the extent practical.

• Frozen reagents should be brought to room temperatureand inverted several times prior to use.

PipetteCalibration Setup

Starting a Pipette Calibration

• At the Main Menu prompt (Figure 1), press YES tobegin the pipette calibration procedure. The Instrumentwill perform a temperature check.

• The Instrument will prompt for lot code (Figure 2). TheInstrument retains up to 6 previously entered lot codes.If the entered code matches one previously entered,press NO and re-enter the code.

• Press YES if entering a new lot code. Group numbersfound on the correct side of the lot code card must beentered. Press ENTER after each group of digits isentered.

• A confirmation prompt will be displayed (Figure 3).Press YES.

• The Instrument will perform a brief self-calibration.Immediately following the self-calibration the Instrumentwill prompt to insert the CAL A vial (Figure 4).

• Open the vial holder cover and insert the CAL A vialpressing down until it meets the bottom of the vialholder.

• The Instrument will then perform a zero check andprompt to remove the CAL A when the test is complete.Return the CAL A vial to the Reagent Kit for future use.

Important Notes:• Use the CAL A vial from the Reagent Kit and not from the Instrument Calibrator Kit.

• Never remove the cover of the CAL A vial.

• The label for the CAL A vial should face the front of the Instrument with the vertical line facing forward.

• Each Blank vial contains a predetermined volume of solution. Any spillage will reduce accuracy.

• The lower portion of the Blank vial must be free of smudges. Touching this area should be avoided.

• Once the Blank vial has been inserted into the Instrument, it must not be turned or moved until the calibrationprocedure is complete for that vial.

• The Instrument will then prompt to insert a blue Blankvial into the vial holder (Figure 5). Remove the Blank vialfrom the vial block and remove the cap.

• Insert the open vial into the vial holder pressing downuntil it contacts the bottom of the vial holder.

• Close the Instrument cover. The Instrument will read theBlank vial.

Important Notes:• The proper range of Sample Solution for the pipette volume to be tested must be used.

• Each Reagent Kit contains bottles of Sample Solution corresponding to various pipette volume ranges.

• If an improper Sample Solution has been dispensed into the Blank vial, the results obtained will not be valid andthe vial is no longer usable. It must be discarded.

• The number of samples that can be dispensed in thisvial, at the selected volume, will be displayed (Figure 9).

• Press YES and the Instrument will display theappropriate Sample Solution to use for the pipettecalibration.

• The Instrument will take a final reading of the Blank vialand then prompt for the first dispense of the SampleSolution with the pipette under test (Figure 10).

Aspirating and Dispensing Sample Solution

Using a plastic transfer pipette, transfer an aliquot of SampleSolution into an aliquot container. Both items are located inthe Reagent Kit. Transfer only enough solution for half-hourincrements. The volume gradations on the transfer pipetteand the 1 mL mark on the aliquot container can be used asa guide for the volume of solution transferred.

• Aspirate the Sample Solution from the aliquot containerwith the pipette under test.

• Lift the vial holder cover and dispense the Sample Solutioninto the Blank vial using standard pipetting technique.

Important Note:The Sample Solution should be dispensed against the inside wall of the vial with the pipette tip placed above themeniscus but below the shoulder of the Blank vial. The vortex mixing action will wash the solution from the insidewall of the vial.

End of Vial

• The number of data points that can be collected in each Blankvial is dependent on the sample volume and will range from 1point to 40.

• Each time a pipette calibration run is completed, theInstrument will display the remaining number of samples of theselected volume that may be dispensed into the vial.

• In any one Blank vial, calibrations may be performed at thesame volume, at different volumes with the same SampleSolution or at different volumes with different SampleSolutions.

• To use the same vial after the completion of the firstcalibration, press YES at the first prompt (Figure 17). Thecalibration cycle will restart.

• When the maximum capacity of the vial has been reached,alternating prompts will flash (Figures 18 & 19).

• If more data points are required, answer YES to the Use NewVial prompt. The Instrument will prompt to remove the old vialand insert a new one. This process may be repeated ifneeded.
